W The primary object of the invention. is to provide a water heater having a: simple,

inexpensivei and.v durable construction wherein theemployment of the usual heating coil orcoils is dispensed with and adapted to accomplish its heating function with-a minimumof applied'heat'and, consequently, with a minimum. of fuel consumption.. I a

A further ob ect is tolprovlde a. device of: the character described all of the water passages of which are. convenlently accessible, as for the removal of scale and sediment.

With these andother objects in view, the

invention resides in the features of construction, arrangement of parts and combnations of elements which will hereinafter be fully described, referencebeing had to the accompanying drawings, forming a part of this specificatiomin which- Figure 1- is a perspective view of the invention with the face plate removed, showing the water passages; Fig. 2 is. a longitudinal section on the line 2-2, Fig. 1; Fig. 3 is an elevation of the invention wlth the back removed,'showing the passages for the products of combustion; Fig. 4 is a longitudinal section of the invention, taken on the line 4."4, Fig. 3;, and Fig. 5 is a transverse section of the. same, taken on the'line55, Fig. '3.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several. viewsA indicates generally a metal body, preferably of cast-iron and having a substantially rectangu'lar form 1n elevatlon.

Said .bodv comprises two parallel vertically disposed side-walls 1, an upper end-wall, 2, and a verticalflat division wall 3, the latter ex- ;tendingfrom: one: of said side-walls to the w istl ne t ase s P arid esen other and being integral therewith. An

body'in'a plane with the front edges of. the side and end walls, the same being designed to have secured thereto, as by means of bolts 5, a cover or face-plate 6. Additional securing bolts, as 5 ,.may. also be directed through said face plate into sockets 19 provided therefor in the adjacent face of said division wall 3, as shown. Said division wall ,3islocated' on'a plane slightly to the rear of the plane of the flange 4, there being thusconstituted between said division wall and said face plate 6 a passage 7 of limited depth. Formed on the rear face of the division wall 3 is a plurality of, substantially rectangular. boX-like upwardly inclined receptacles 8rwhich open outward through said face pl-ate, the interiors of said receptacles constituting water-receiving pockets 17. Said receptacles are disposed in staggered relation, alternate receptacles being extended laterally from the opposite side walls, 1. Each receptacle terminates at a distance from the side wall opposite that from, whichit is projected, there being thus constituted between said, receptacles at the rear of the division wall 3 a tortuous passage for the products of combustion, as is indicated by arrows in Fig. 3.

A back 9,. preferably of sheet-metal, is suitably attached, as by screws, to therear edges of the side and end walls of thebody,

an asbestos board 10 being preferablyinterposed between said back and the passages inclos'ed thereby for the products of combustion. Said back is extended at its lower end in curved form to provide a partial inclosure 11 for a gas burner 12which mav be of anv suitable form or type.

As is obvious, heat emanating from the burning gas ascends to a suitably located discharge passage 13 through the tortuous passage indicated bv arrows in Fig. 3, being deflected back and forth by the receptacles8. The walls of said receptacles and the flat division wall 3 are effectually heated by direct contact therewith of the ascending products of combustion, and much of this heat'is absorbed by the water which enters the lowermost of the pockets through .a

suitably located passage, as 14. and thence passes outward over the face ofthe division wall, whence 1t follows a tortuous course, as

indicated by arrows in Fig.1, to a discharge passage 15 located. in the upper end wall 2, being deflected back and. forth acrosssaid division Wall and into-thevarious; pockets by ing side walls, vertical'division wallexsideand end walls. a

When the water'passagesbecoine clogged with-sediment orfwith excessive accumulations' of lime, access'may fb'e readily'had' to thewater passagesrby simply removing'the face-plate16:,"whereupon a chiselor other tool may bejconveniently used for removing said accumulations, 'As is obvious, therefore, no
